Breedig performance of three threatened bata fish

A study was conducted to observe the breeding performance with maturing stages and nursery practices of the threatened indigenous fish species Labeo gonius, Labeo bata and Cirrhinus reba at Arabpur Fish Farm (Longitude: 89°12 15 East; Latitude: 23°10 30 North), Jessore, Bangladesh during 1998 to 2002. Trial doses of PG used for induced breeding of Labeo gonius, Labeo bata and Cirrhinus reba were 0.5 to 5.0; 1.0 and 2.0 to 4.0mgPG in the first dose, and 4.0 to 8.0; 1.0 to 8.0 and 00 to 7.0mg in second dose for female, respectively. The male fishes were administered only a single dose of 2.0; 1.5 and 1.0mgPG, respectively. Induced breeding can successfully be done in Labeo gonius with 3.0mg of PG/kg body weight in first dose and 7.0mg in second dose for female and a single dose of 2.0mg for male for virgin fish; in Labeo bata with 1.0mg of PG/kg body weight in first dose and 5.0mg in second dose for female and a single dose of 1.5mg for male of virgin fish; in Cirrhinus reba with 2.0mg of PG/kg body weight in first dose and 6.0mg in second dose for female and a single dose of 1.0mg for male of virgin fish.
